Question

Can anyone tell me question 1 and 2 ?? i will mark it as brainliest answet

Answer 1

Q#2.

POLAR COVALENT COMPOUND

polar covalent compounds are those compounds that are formed by unequal shairing of electrons between elements.

FOR EXAMPLE:

⇒H2O;  H⁻O⁻H

in this molecule O shares two electrons and H shares 1 electron.

⇒HCl;  H⁻Cl

in this molecule Cl molecule is more electronegative than hydrogen,therefore do not share its electron with hydrogen completely. hence cl develope partial negative charge and hydrogen develope partial positive charge.

NON-POLAR COVALENT COMPOUNDS:

non polar covalent compounds are those compounds which are formed by equal shairing of electrons.

FOR EXAMPLE:

⇒H2          H⁻H

⇒Cl2           Cl⁻Cl

Q#1:

⇒HCl;  H⁻Cl

in this molecule Cl molecule is more electronegative than hydrogen,therefore do not share its electron with hydrogen completely. hence cl develope partial negative charge and hydrogen develope partial positive charge.
